type rating done in US:
It might work. There are a few in Tiger who did it. Biggest problem is that you need a license entry for the A320, i.e. your base training (landing training). This is the most expensive part of a type rating.
It all depends on supply and demand, you might get a job, but there might be others around who have the experience or who pay the 60 000S$ training bond.
